Twisted pair communication cables with additional conductive wires

Abstract

A twisted pair cable may include a plurality of twisted pairs of individually insulated wires and at least one additional wire. Each additional wire may include a conductor and at least one layer of enamel insulation material or insulation formed from a thermoset material formed around the conductor. A jacket may be formed around the four twisted pairs and the at least one additional wire.
